29. Dark Axion Portal

Hye-Sung Lee (KAIST)

The dark matter sector is mysterious. One possible scenario is the dark matter sector is basically separated from the visible sector and is made up of its own particle spectrum similar to the standard model. Here, the concept of the portal between the dark sector and the visible sector is important to investigate the dark sector. We will talk about the dark axion portal, which connects some...

15. The Migdal effect in liquid noble dark matter experiments

Dark matter direct detection experiments have spurred interest in the Migdal effect, where it is employed to extend their sensitivity to lower dark matter masses. The calculation of the signal is subject to large theoretical uncertainties, therefore a calibration of the Migdal effect and the experimental response to a potential dark matter signal is needed. In this talk I'll show the results...

55. Direct Detection of Low Mass Fast Moving Dark Matter

Low mass fast moving/energetic dark matter (DM) is very well motivated and has been a subject of attention in the literature. These fast-moving particles can gain enough kinetic energy to pass the thresholds of some Large volume terrestrial detectors. For instance, fast-moving or "boosted" DM can account for the recent excess in electron recoil events observed by the XENON1T detector, due to...

11. Astrophysical signatures of axion-like-particle clumps

Axion-like-particles frequently appear in extensions of the Standard Model and could be a principal component of the dark matter in the universe. We review several astrophysical effects that could be due to inhomogeneous axion distributions. Such clumps could have been present at early stages of the evolution of the universe giving rise to the formation of black holes; or they could exist in...

61. Deep Learning Models of the Galactic Gamma-ray Emission and Implications for the Galactic Center Excess

Simona Murgia (University of California, Irvine)

25. The Search for Dark Matter in the Ultra-high-energy Sky

Mehr Un Nisa (Michigan State University)

The nature of dark matter (DM) — the cold, neutral entity comprising roughly 85% of all matter content in the universe — is one of the biggest open problems in modern astrophysics. One plausible class of candidate DM particles, from beyond the Standard Model of physics, are Weakly Interacting Massive Particles (WIMPs), ranging in masses between ~GeV to hundreds of TeV. Such DM particles may...
